Calmodulin kinase inhibition prevents development of the arrhythmogenic transient inward current.


Although it is widely accepted that afterdepolarizations initiate arrhythmias when action potentials are prolonged, the underlying mechanisms are unclear. In this study, we tested the hypothesis that action potential prolongation would raise intracellular calcium and thereby activate the arrhythmogenic transient inward current (Iti). Furthermore, given that… (More)
